Construction method of pre-embedded cable pipes for fan foundation in mountainous wind power projects

Abstract

The invention discloses a construction method for pre-embedded cable pipes for fan foundations in mountainous wind power projects. Eight CPVC cables with a diameter of 125 mm and one CPVC cable pre-buried pipes with a diameter of 50 mm are reserved in the fan foundation. After positioning, use cables to pass through the cable fiber from the fan side along the cable pre-buried pipe to the box-type transformer, so as to transmit the electric energy generated by the fan rotation to the box-type transformer, including fan foundation excavation and pre-buried cable pipe groove excavation , Pre-embedded cable tube installation, pre-embedded cable tube nozzle sealing, concrete pouring, cable laying and other steps, adopt the two-layer connection method of internal glue bonding and external tape sealing, so that both sides of the pre-embedded cable tube are sealed tightly, Prevent concrete and other debris from entering the buried pipe; use three rows and five rows of steel brackets to fix the cable pipe to prevent the pre-embedded cable pipe from flowing into the gap of the pre-embedded cable pipe and the concrete below to cause the pre-embedded cable pipe to float. It is suitable for pre-embedded cable pipes in fan foundations in mountainous areas laying construction.

Description

Technical field: [0001] The invention relates to a construction method of a fan foundation, in particular to a construction method of pre-embedded cable pipes for a fan foundation in a mountainous wind power project. Background technique: [0002] With the steady development of my country's new energy industry, wind energy, as an important part of new energy, has many advantages such as renewable, non-polluting, and widely distributed in my country. Wind power generation has received strong support from the state. In recent years, the construction of wind power projects in my country has developed rapidly. However, there are uncertain factors in the development of wind power generation. Some wind power generation projects are distributed in mountainous areas. In mountainous areas, there is a problem of how to transfer the power generated by the wind turbine to the box-type transformer. , How to ensure the quality of the embedded cable pipes in the fan foundation, how to arran...
